15 kinds of flavonol glycosides in the tea plant were identified by HPLC-TOF-MS.
An method by MRM mode of UPLC-QQQ-MS/MS to quantify flavonol glycosides in the tea plant was established.
The method by MRM mode of UPLC-QQQ-MS/MS possesses the features of more rapidness, sensitivity, and selectivity compared to HPLC method.
Flavonol glycosides are mostly accumulated in young leaves.
